This spindle bearing carries a 25° contact angle and hybrid construction with ceramic balls, giving a bore of 70.0 mm, outside diameter of 100.0 mm and width of 16.0 mm, at a net mass of 0.322 kg. The cage is executed in version T, and the bearing is supplied without sealing, requiring an external arrangement for lubricant retention and contamination protection. Restricted tolerances place it in the P4S accuracy class, suited to running at elevated speeds with tight geometric control. Being an adjusted unit, it is intended for mounting in pairs or sets, with the specified contact angle allowing combined radial and axial load support along a defined line of action. The absence of integrated sealing means grease or oil lubrication must be supplied and contained through the housing design, while the P4S tolerance grade supports precise shaft location and reduced running deviation under high-speed operation.
